Polkadot is a multi-chain framework that enables interoperability and scalability for multiple blockchains. See: https://github.com/paritytech/polkadot-sdk
Hardware requirements can be found here: https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#standard-hardware
Start the service with 'sudo snap start polkadot-parachain'
Check logs from the Polkadot parachain service with 'snap logs polkadot-parachain -f'
Supported configuration options for the snap:
service-args [default=--base-path=$SNAP_COMMON/polkadot_base --name=<hostname>] For available arguments see https://github.com/paritytech/polkadot-sdk The value set here will be passed to the Polkadot parachain binary with a few exceptions listed below.
$SNAP_COMMON/polkadot_base and is not allowed to be configured.endure [default=false] If true the Polkadot parachain service will not be restarted after a snap refresh. Note that the Polkadot parachain service will still be restarted as the result of changing service-args, etc.
Use this when restarts should be avoided e.g. when running a validator.
Example config for running on Polkadot parachain with an RPC endpoint on port 9933:
sudo snap set polkadot-parachain service-args="--name=foobar --chain=polkadot --rpc-port=9933"

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Polkadot Parachain, simply use the following command:
sudo snap install polkadot-parachain
Browse and find snaps from the convenience of your desktop using the snap store snap.
